I'm glad Tatum was mature in his answer to this, but in the end I don't think it means much other than that he is wise beyond his years, something we already knew. I think he would be okay coming off the bench if Brad wanted him too, but I don't think that's likely. The best unit to start is clearly Irving, Brown, Tatum, Hayward, and Horford, something Brad had determined to start last season. Unless Hayward's recovery isn't far enough along yet, I expect that will be the lineup this upcoming season as well and I'm a bit surprised that anyone would think otherwise. Not that people can't suggest other lineups and give their reasons, but I don't regard any other starting lineup as likely at this point.
